2 ATTORNEY Patented Oct. 12, 1937 UNITED STATES PATENT .OFFICE I f j2,095,414 t p r SHOULDER SPREADERFOR ROADWAYS w David A; Hemstreet andJseph W Bell, a Marysville, Calif Application March 9,1932, Serial No.597,703 Claims. (01. 94-44) V :The invention relates to road buildingmachinery and particularly to a means for building up roadways along theedges or shoulders thereof.

' An object of the invention is to provide an 5 apparatus of thecharacter described having a' material discharging capacity in excess ofthe quantity to be deposited so as to insure at all times freedom offlow during the normal advance of the apparatus over the road but at thesame time'the flow will be held to the desired amount by the roadclearance of 'the orifice and the means provided on the machine forleveling the deposit. v

Another object of the invention is to provide a machine of thecharacter. described having a material leveling means which is arrangedto cooperate with the material discharge orifice to control the flow ofmaterial from the latter.

Still another object of the invention is to provide a road shoulderspreader in which the material discharge orifice is located in thebottom thereof whereby the material will be discharged directlydownward. 1 a i i i A furtherobject of the invention is to provide anapparatus of the character described which is arrangedto be supported ona bed for the new fill as well as on the roadway. 3 A 'stillfurtherobtiect" of the invention is to provide a shoulder spreader which willbe positively guided in respect to its position over the portion to-befilled during the advance of the spreader thereover. V p

Yet another object of the invention is to provide an apparatus of thecharacter described which is extremely simple and inexpensive inconstruction, may be readily adjusted to lay a fill of any slope,permits the ready interchange of parts, and is readily convertible foroperation with or against traflic. 40 The invention possesses otherobjectsand features of advantage, some of which, with the foregoing,will be set forth in the following description of the preferred form ofthe invention which isillustrated in the drawingaccompanying and 45forming part ofjthe specification; Itis to be understood,however,thatvariations in the showingmade by the said drawing anddescription maybe adopted within the scope of the invention as set forthin the claims. V

Referring to said drawing: a

disposed of a bolt 16.

Figure 3 isan end elevation of, the spreader as shown in Figure 1.

In the embodiment of the invention illustrated the spreader 2 is shownin position for depositing material on theshoulder 3 of the roadway 5,the shoulder being depressed todefine a subplanar strip contiguous withthe edge of the roadway. The spreader comp-rises a hopper 1 arranged ina frame 8 which is supported on runners 9 and II]. The runner 9 includesa shoe l2 and uprights [3 which extend upwardly from theshoe and arearrangedfor adjustable positioning to the frameat the front and rearsides of the hopper, the connection between the uprights and the framebeing preferably by means The uprights are provided with verticallyaligned holes ll, any one of which may be engaged by the bolt forobtaining different vertical positioning of the hopper with respect tothe shoe. .Also the frame 8 is provided with horizontally spacedopenings IQ for engagement by the bolt, so. that transverse adjustmentas well as vertical may be effected. between the hopper and the runner.The runner 9 is arranged to bear on the roadportion 4 adjacent the edgethereof and means are provided; whichare here shown preferably inconnection with such runner, for engaging the side edge 2| of theroad soas to hold the spreader in desired position over the depressed strip astheformeris advanced thereover. As here shown such means comprisesa'guide plate 22 .which is fixed to the shoe and extending verticallydownward from the adjacent inner edge thereof.

.The. runner I0 is disposed at the end of the hopper opposite the runner9, and as will be clearly noted from Figure 1 the shoe 23 of the runnerH) extends under the hopper and is arranged to ride in the bottom of thedepression. With the runner l0 thus disposed in the depression thespreader may be properlysupported for smooth traction over the area tobe filled with tlie'material from the hoppenand in order to permit theunobstructed flow of the material from the hopper orifice 251to the roadbed, the

rear end of the shoe 23 preferably extends rearwardly only partiallyunder the orif ce. Attachment of the shoe 23 of the runner l0 to thefr'ameis effected by means of an upright 24 whichis fixed to the shoeandadjustably secured to the frame by a bolt- 26 for variable verticalpositioning in a manner similar to the connection of the uprights'l3with the frame. Since the shoe 23. is as here showndisposed'no furtherrearwardly than. the dischargeqorificew of the hopper, the runner I0 ispreferably Supported exclusively at the front of the hopper. Thereforebut one upright 24 is disposed at the front of the hopper as clearlyshown in Figure 3. Preferably, in order to compensate for the omissionof an upright at the rear, the forward end of the shoe is secured to theforward upper edge of the hopper by means of a link 21, the latter beingof adjustable length to allow of variation in the vertical positioningbetween the hopper and shoe as aforesaid.

As an effective means for removing from in front of the advancinghopper, any earth which may have shifted back upon the strip from theloose embankment at the outer edge thereof, we provide a deflectingplate 28 which is secured to the hopper by means of a brace 29 andpreferably afilxed at its forward end to the corresponding end of therunner Ill. The runner I0, as will be noted in Figure 2, is disposedappreciably inward from the outer end of the discharge orifice, and thedeflecting plate extends from the runner to a point without said end ofthe orifice so that the material discharged from the hopper will notencounter the earth aforesaid.

The runners 9 and ID are arranged for changeable positioning so that thespreader may be operated to advance in either direction on the same sideof the road. This is enabled by the similarity of the runner attachingmeans at the ends of the frame. To effect an interchange of the runnersthe shoe 9 is moved laterally from one end of the frame to the other andreversed, while runner I0 is merely placed at the end from Which therunner 9 has been removed.

The discharge orifice 25 of the hopper preferably comprises the entirebottom of the hopper and, being thus directly at the bottom of thehopper instead of at the side thereof, the material may thus fiowstraight downwardly upon the strip. Furthermore, with the orifice thuspositioned it may be arranged to pass over the strip with all portionsthereof in extremely close proximity to the surface of the strip. Inthis manner the orifice may be of relatively large size to permit theready discharge of material from the hopper, but at the same time owingto the nearness of the entire orifice to the strip the flow will begoverned to a great extent proportionately to the speed at which thehopper is advanced. A manual control for regulating'the volume ofmaterial discharged from the hopper independent of the advance movementof the spreader is afforded by means of a gate 3| movable coplanar andalong the inner side of the rear wall 32 of the hopper. Movement of theplate to effect the desired variation in the size of the opening andlocking of the plate in said position is afforded through means ofcranks 33 connected to the gate by means of link rods and operativelyassociated with a worm gearing 34 which is mounted on the hopper and maybe actuated by means of a handle 36. The links 35 which are disposedadjacent opposite ends of the gate are each adjustably connected totheir associated crank arms whereby different variations in thepositioning of the gate with respect to the orifice may be effected soas to thereby secure any desired slope of the fill surface. It isimportant to note that the gate projects downwardly from the hopper toan appreciable degree, proportionately to the closing of the orifice bythe gate. In this way the bottom of the gate will provide an effectivemeans for automatically levelling the material as it is deposited on thestrip to the desired depth and slope.

A draw bar 38 is secured to the upright members I3 and 24 in such manneras to allow lateral and vertical adjustment of the former. In order tofill in with earth from the embankment at the side of the strip anyspaces along the side of the deposit on the strip, a deflecting member39 is secured to the frame 8 at an end thereof adjacent the runner ID.
